How do we know our faith can overcome fear?

The assurance that faith can overcome fear rests on the nature of God and His promises. In Hebrews 11, Moses is a prime example of someone whose faith enabled him to act courageously despite overwhelming external threats. God, who is invisible yet omnipresent, provides strength and redemption to those who believe. Through faith, believers can recognize the temporary nature of worldly fears and cling to the eternal truths of God's Word, thus enabling them to act in accordance with His will rather than succumbing to the pressures of man.
